We have the eureka and the cordless dyson. Our dyson is a model or two above the HL supplied models. It works ok but has to be emptied daily.
The central vac works great too. I added to the piping, installed a muffler and plumbed it to the outside. With a beater bar it does a good job.
Since HL no longer offers it as an option, I would most likely install the eureka in the next rig, and also plumb it outside.
